| 摘 要： | 西藏隆子县境内古滑坡分布广泛,近年来有复活的趋势。在分析一典型古滑坡——当来木古滑体变形特征的基础上,对古滑体的复活成因进行了深入研究。结果表明,古滑体的变形破坏及其疏松的物质组成是滑体复活的首要原因;其次是对古滑体的认识不足,修建民房时未对古滑体采取必要的防治措施,过度的坡后加载为古滑体的复活埋下隐患;再次是水对滑体的积极诱发作用,致使滑体产生推压变形破坏,从而激发了古滑体的复活。

| Abstract: | Fossil landslides distribute broadly in Longzi county.And the trend of reactivation appears lately.Based on the deformation analysis of Danglaimu fossil landslide,the reasons for sliding were studied.The results show that the first reason is the loose rock-soil constitution and deformation of fossil landslide.The second reason is that there were no measures of prevention and cure for fossil landslide during building construction.The last reason is that the original balance of fossil landslide is destroyed.These can offer some references to keep Longzi country from the calamity of fossil landslide. |
